Female rats genetically engineered to carry a deficient Mecp2 gene — whose mutations are the leading cause of Rett syndrome — show social, behavioral, and motor symptoms that are similar to those of humans with the neurodevelopmental disorder, a study reports. These symptoms were associated with low levels of the…

The copy number of mitochondrial DNA (mtDNA) is increased significantly in patients with Rett syndrome, possibly indicating mitochondrial dysfunction, a study reported. Researchers suggest that this increase in the copy number of mtDNA is an attempt to compensate for decreased energy availability. Mitochondria are the producers of energy within…
Impaired function of the MeCP2 protein — the most common cause of Rett syndrome — causes defects in a process called RNA splicing, affecting protein production from genes important for nerve cell communication. The study with that finding, “Rett syndrome linked to defects in forming the…
Novartis announced it is scrapping plans to move OAV201, an investigational gene therapy for Rett syndrome, into clinical trials. “The totality of the pre-clinical data [on OAV201] does not support a path forward to human clinical trials,” according to the company’s third quarter report for this year.
Hive Networks, a digital health company, is teaming up with the International Rett Syndrome Foundation (IRSF) to provide a cloud platform to support patients, caregivers, and researchers in the Rett community. The multi-year partnership — being announced in the midst of Rett Syndrome Awareness Month — aims to…
Binding to the zinc finger protein 483 (ZNF483) may move the MeCP2 protein — defective in most cases of Rett syndrome — away from the cell nucleus, which likely affects gene activity in nerve cells, a lab study suggests. These findings shed light on the potential processes regulating the…
A comprehensive communication intervention package improved the expressive communication and/or visual attention of three women with Rett syndrome, a small study shows. These findings suggest that the intervention — which combined aided language modeling (ALM), responsive partner strategies, and a gaze-controlled device — may be beneficial for this patient population.
A clinical trial evaluating oral Anavex 2-73 in children and teenagers with Rett syndrome is recruiting up to 84 girls, ages 5 to 17, at a center in Vancouver, Canada, and three sites in Australia. According to a press release from the Ontario Rett Syndrome Association, the British Columbia Children’s…
Supporters worldwide are marking Rett Syndrome Awareness Month, set aside each October to bring attention to Rett syndrome, a rare neurodevelopmental disorder that’s estimated to affect 1 of every 10,000 girls, and fewer boys. From posting on social media to sporting temporary tattoos, participants globally are raising awareness and…
The European Commission has granted orphan drug designation to TSHA-102, an investigational gene therapy for the treatment of Rett syndrome. The designation encourages the development of medicines to diagnose, prevent, or treat life-threatening or debilitating diseases that affect fewer than five in 10,000 people living in the European…
